DEWALT 20V MAX XR Cordless Hammer Drill Driver and Impact Driver Combo Kit Review: Professional-Grade Power in Your Hands

After spending two weeks putting the DEWALT DCK249E1M1 combo kit through its paces on various projects, we’re confident this powerhouse duo delivers exceptional performance for both professionals and serious DIYers. This premium kit combines DEWALT’s renowned build quality with next-generation battery technology, creating a versatile toolkit that handled everything we threw at it.

What’s in the Box: Complete Professional Setup

Opening the sturdy carrying case reveals a thoughtfully organized kit containing:

• DCD809 20V MAX XR Brushless Cordless Hammer Drill Driver
• DCF850 20V MAX XR Brushless Cordless 1/4-inch Impact Driver
• 1 DCB204 20V MAX XR 4.0Ah Lithium-Ion Battery
• 1 DCB203 20V MAX XR 2.0Ah Lithium-Ion Battery
• DCB112 Charger
• Belt hooks for both tools
• Durable carrying case

First Impressions: Build Quality That Inspires Confidence

From the moment we lifted these tools from their case, the premium construction was evident. Both tools feature DEWALT’s signature black and yellow professional design with rubberized grip areas that provided excellent comfort during our extended testing sessions. At a combined weight of just under 6 pounds (with batteries), they strike an ideal balance between substantive feel and all-day usability.

Why This Combo Kit Outperforms the Competition

During our hands-on testing, several features immediately distinguished this kit from similar offerings:

• The brushless motors in both tools delivered noticeably longer runtime and higher performance compared to brushed alternatives
• The hammer drill’s 3-speed transmission allowed precise control across different materials
• The impact driver’s 3-speed settings provided the versatility to handle everything from delicate cabinet hardware to heavy lag bolts
• Both tools feature integrated LED work lights that effectively illuminated our workspace during testing

Hammer Drill Deep Dive: Power Meets Precision

The DCD809 hammer drill immediately impressed us with its 340 UWO (Unit Watts Out) power rating. When drilling through concrete during our testing, the hammer function delivered smooth, efficient performance without the excessive vibration we’ve experienced with competitor models.

The 3-speed gearbox provided excellent versatility:

• Speed 1 (0-450 RPM): Perfect for driving large fasteners and high-torque applications
• Speed 2 (0-1,300 RPM): Ideal balance for general drilling in wood and metal
• Speed 3 (0-2,000 RPM): Delivers high-speed performance for smaller diameter drilling

The 1/2-inch ratcheting nitro-carburized metal chuck provided rock-solid bit retention throughout our testing, even under high-torque applications.

Discover Uncompromising Performance for Your Projects

During our testing on pressure-treated lumber, the hammer drill drove 3-inch screws with ease, requiring minimal pressure and maintaining consistent control. When we switched to drilling through metal, the variable speed trigger allowed precise control for clean, accurate holes without walking or binding.

Impact Driver Analysis: Compact Powerhouse

The DCF850 impact driver may be compact at just 5.1 inches in length, but it delivers impressive performance. The 1/4-inch hex quick-release chuck made bit changes effortless during our rapid-fire testing between different fastener types.

What truly set this impact driver apart was its 3-speed electronic transmission:

• Speed 1: 0-1,000 RPM, 0-1,200 IPM, 500 in-lbs
• Speed 2: 0-1,800 RPM, 0-2,500 IPM, 1,200 in-lbs
• Speed 3: 0-2,850 RPM, 0-3,250 IPM, 1,825 in-lbs

This versatility allowed us to use Speed 1 for precision work on cabinet hardware, while Speed 3 effortlessly drove 4-inch lag bolts into dense hardwood during our deck repair test.

Battery System: Extended Runtime When You Need It Most

The included batteries provided impressive runtime in our continuous use tests:

• The 4.0Ah battery powered the hammer drill through approximately 130 2-inch holes in pine before requiring a recharge
• The 2.0Ah battery drove roughly 220 2-inch screws with the impact driver on a single charge

We particularly appreciated the fuel gauge indicators on both batteries, which provided accurate remaining power readings throughout our testing.

The included charger replenished the 2.0Ah battery in approximately 40 minutes and the 4.0Ah battery in about 90 minutes during our timed tests.

Transform Your Workflow with Professional-Grade Tools

The compatibility with DEWALT’s extensive 20V MAX ecosystem means these tools can share batteries with over 200 other DEWALT products – a significant advantage we’ve appreciated when working with multiple DEWALT tools on larger projects.

Ergonomics and Handling: Designed for All-Day Comfort

After using both tools for extended periods during our testing, the ergonomic design distinctions became clear:

• The textured rubber overmold grips provided excellent control even with sweaty hands during our summer outdoor testing
• Both tools are well-balanced, with weight distributed to minimize wrist strain
• The strategically positioned LED lights effectively eliminated shadows when working in tight spaces
• The belt hooks proved invaluable during ladder work, allowing quick tool access without descending

Value Assessment: Premium Performance Justifies the Investment

While this kit represents a higher initial investment than some entry-level alternatives, our testing confirmed the value proposition. The professional-grade construction, versatile performance across applications, and compatibility with DEWALT’s extensive ecosystem make this a smart long-term investment for anyone who values quality tools.

Based on our durability testing and DEWALT’s reputation for longevity, we expect these tools to provide reliable service for many years, effectively amortizing the initial cost across countless projects.
